Introduction: The purpose of this study was to clarify the influence of clenching strength on interocclusal registration using intraoral scanner (IOS).
Methods: Subjects were eight volunteers. Two experimental conditions were light clenching (LC) and 40% maximum voluntary clenching (MVC). The conventional silicone bite registration and IOS were used for comparison. Occlusal contact areas (OCA) for different clenching strengths were compared, along with variation of measured values (VMV) between recording methods.
Results: Significant differences were observed between conditions on OCA and between methods on VMV.
Conclusion: Clenching strength influenced interocclusal registration using IOS. Int J Prosthodont. 10.11607/ijp.8445.
